How to study opening theory

I am looking for books/youtube videos/dvds on how to play these openings. If anyone has a good reference, please let me know. I need material on:

KID as white

Benoni as white

Dutch Slav as black

Caro Kann as black

Bird as black

Dutch defence as white

Uhm, some of what you are putting up there doesn't make sense, and others need to be more specific:

KID as White - Not all books are geared toward one specific player.  A lot depends on what line youa re looking to play:

• Grandmaster Repertoire 1 and 2 (1 covers all d4 d5 lines, 2 covers everything else.  Fianchetto System is used against most defenses (Catalan, Fianchetto KID, Fianchetto Grunfeld, Fianchetto Benoni, Fianchetto Variation of the Benko Gambit, Fianchetto main lines against the Dutch, etc.
• The Classical King's Indian Uncovered - Objective, not a White repertoire.

Benoni as White for the most part covered as well.

"Dutch Slav" as Black - Uhm, doesn't exist.  Either it's a Dutch (1.d4 f5 or 1.d4 e6 intendng 2...f5), or it's a Slav (1.d4 d5 2.c4 c6).  It's not both.  Dutch can be Stonewall, Classical, Leningrad, etc.

Caro-Kann as Black - a lot depends on what line you want to play against the main line.  The Caro-Kann Move by Move covers 4...Nd7, The Grandmaster Repertoire book on the Caro-Kann advocates 4...Bf5.

Yeah I think the entire 6.e3 line is generally referred to as the Dutch Variation

Here is my advice on how to study opening theory:

read the forums looking for threads that have "opining(s)" in the title, and only listen to people with sub-1200 ratings. 

And forget aboout the openings you mentioned unless it is recommended by one of the sub-1200 experts on this site.

generally a good way to go, also if there is a massive flame war going on over a particular opening (such as the KG) pick the side with the least logical thought process, and have fun

On a more serious note, sharpen your repetoir.

you know what they say, those who can't play chess, teach opinings.

Yes, 6.e3 is the "Dutch Variation" of the Slav Defense.  However, it's never referred to as the "Dutch Slav", probably because of the confusion of the Dutch Defense and the Dutch Variation of the Slav Defense.

That said, learning only the Dutch Variation of the Slav Defense for Black won't do you a lick of good without learning the rest of it.  If you are looking to play the Slav Defense as Black, "The Slav: Move by Move" by Cyrus Lakdawala is a good book with one exception.  In it's either game 16 or 17, he advocates ...e5 around move 15 or 16, but that move is a mistake.  Otherwise, the book is great.

The first chapter is on the Dutch Variation, but if you are going to play this as Black, you must also know the Central Variation (6.Ne5), Early e3 lines (3.Nc3 and 4.e3 or 3.Nf3 and 4.e3), the Exchange Variation, etc, otherwise, knowing the Dutch Variation won't do you a lick of good.

Had this been the White side you intended to play, then you'd also need to know the a6-Slav.

It sounds like what you ultimately need to do is scrap your original plan, and instead, post what openings you are trying to learn.  This means a complete defense to 1.e4, a complete defense to 1.d4, and then only as White do you mention certain variations.

The reason is simple.  Let's hypothetically say you chose the Slav and Petroff as Black.  You need to know the complete Slav.  But you don't need to know anything about the King's Indian or Dutch or Grunfeld or QGA.  As White, it's the opposite.  Let's say you are a d4 player.  You need to have a line against the KID, Grunfeld, Dutch, Benoni, Benko, QGA, QGD, Slav, Semi-Slav, etc.  That said, you don't need to know every line of the KID, just one of them, whether it be the Fianchetto, Classical, Saemisch, etc.

So first figure out the general openings you plan to play, like maybe the Slav, Petroff, and 1.d4.  Then, for White, figure out what variation you want to learn against each possible defense, and post the list here.  We can help you a lot better that way.

For example, here's what I play:

Black:  Dutch, Tarrasch Defense, and Modern against 1.d4, Caro-Kann, 1...e5, and Modern against 1.e4

White:  1.e4, 1.d4, and 1.Nf3.  With 1.e4, I play Advance French, Both Classical and KIA against Caro-Kann, 2.a3 Sicilian, Three Knights/Four Knights Game against 1...e5, Classical Alekhine, Austrian Attack againt Pirc/Modern.  With 1.d4, Catalan and Slav against 1...d5, Trompowsky against 1...Nf6.  With 1.Nf3, Catalan and Slav against 1...d5, English against 1...c5, Fianchetto KID/Grunfeld/Benoni against 1...Nf6 with possible transpostions to the Catalan if ...d5 is played early on by Black.

I agree with ThrillerFan's post above.  It's very good advice.

I don't really watch much opening stuff on youtube. They make claims about things that I never hear GMs make. Every position just happens to be plain favorable for White or equal for Black with no explanation of their claims. 

I usually watch games on youtube and just try the things I see there. The videos with whole games are almost always better in my view.

YouTube is utter crap when it comes to chess.  Books, Articles, and DVDs by GMs and IMs are far more reliable than the garbage you see on YouTube.
